Since its implementation a few years ago, the Doing It Right (DIR) philosophy has gained in popularity not only in the cave diving community and amongst technical divers, but it has also spread to the recreational diving community across the world.

Global diving travel has become increasingly easy over the last decade or so, providing easy access to a growing number of tropical and exotic destinations. So, for many divers residing in cooler climates or new to the sport, it is tempting to look only towards these warm distant destinations and perhaps ignore the wealth of marine life on their own doorstep.

Just like GirlDivers don’t go under the waves without our “life support system”, we shouldn’t go under the rays without a “life support system”. Yes, ladies (and gentlemen), we’re talking about sun protection. And while sometimes this topic seems over played, hopefully this article will share new information and remind you of the need for adequate skin care under the sun.

There is no such thing as safe technical rebreather diving without proper preparation. But preparation means much more than just checking equipment, going through dive planning and “What-ifs”. It is also a matter of long-term preparation.

The way an animal gets around in the sea and or in the air depends, fundamentally, on the density and viscosity of its milieu.

A conversation with technical diver and depth record breaker, Pascal Bernabé. Pascal Bernabé has just held a press conference at the Moscow dive show answering questions from an enthusiastic audience about his 330 meter record dive.

The soft spoken Frenchman seems relieved to slip out of the uncomfortable limelight on the stage. Having escaped the massive attention for a while, he grabs a chair beside me, and we begin to converse about the meaning of it all.

Imagine a beautiful shallow green water reef with kelp, anemones and sponges among which lots of colourful fauna darting in and out and. Now imagine that the reef is growing on some weird sandstone arches and that the water is fizzy like sparkly mineral water, with bubbles coming out of the reef structure.

If there is any hidden secret in the Mediterranean, it is the island of Vis. For many years, it was a forbidden and restricted military area. It was not until 1991, when the iron curtain finally came down, that it was opened up for tourism and diving. On Vis, small picturesque port towns and spectacular wrecks, drop-offs and caverns are waiting to be discovered by divers.

Why the peculiar head shape of the hammerhead shark developed as it did has been the subject of much speculation. Few other morphological oddities have inspired so many fanciful and sensible theories about its function as the weirdly shaped head that characterises the hammerhead shark. Recent experimental evidence supports some ideas and refutes others, while pointing to a previously unsuspected role for this peculiar feature.
